Area Forecast Discussion National Weather Service Melbourne FL 354 PM EDT Thu Sep 23 2021

DISCUSSION.

Currently-Tonight . Weak front south of Orlando will continue a slow progression southward toward Lake Okeechobee region into late tonight. Showers and storms will continue to develop into the late afternoon and early evening, with greatest coverage expected south of a line from Orlando to the Cape where greater moisture along to south of the front will reside. Scattered to numerous convective coverage is possible across this region, as well as a few stronger storms. This activity will weaken this evening, with only a slight chance for onshore moving showers and possible a storm or two along the coast, south of the Cape into tonight.

Drier air north of the front should allow temperatures to drop below the 70 degree mark for some locations near to north of Orlando since June 1st of this year. Min temps in this region are expected to fall to the mid to upper 60s. However, farther south lows will remain in the low 70s. Could see some redeveloping stratus and patchy fog across Okeechobee County and the Treasure Coast closer to the front late tonight.

Friday . Front will remain stalled near the Lake Okeechobee region into Friday. Greater moisture along this boundary will continue higher rain chances (up to 50-60 percent), mainly across Okeechobee County and the Treasure Coast into the afternoon, with drier conditions north of Orlando. This will lead to a rather tight moisture/PoP gradient across the area. Highs will reach the mid to upper 80s, though dew points in the 60s from Osceola County northward will make it feel drier, with dew points in the low/mid 70s continuing humid conditions farther south.

Modified Previous Discussion .

Saturday . The weekend starts off wetter for the far southern areas as the stalled front remains, with rain chances up to 40-50 percent across Okeechobee County and the Treasure Coast. Drier air north of Orlando should keep rain chances out of the forecast across this region, with only a low chance of rain (20-30 percent) from Orlando to the Cape southward through southern Brevard/Osceola counties. Again, this will all depend on how far south the initial surge of dry air makes it, with a tight moisture gradient likely to still be in place making the rainfall forecast difficult and uncertain.

Sunday-Wednesday . A large upper-level trough will move across the eastern CONUS on Sunday causing a reinforcing cold front to move through Central FL Sunday afternoon. While no temperature changes occur, this frontal passage will bring in much drier air and push out any lingering moisture/shower activity. High pressure builds across the Southeastern U.S. giving us a period of mostly dry conditions Monday and Tuesday, as only a marginal 15-20 percent chance of rain exists across the southern areas each afternoon. Moisture increases slightly Wednesday, as low 70s dew points with scattered showers and isolated storms return to the forecast.

Highs each afternoon will reach the upper 80s to around 90 degrees, but with dew points in the 60s it will be a manageable heat through mid week. Morning lows Monday/Tuesday in the upper 60s to around 70 degrees for inland areas, and low 70s along the coast.

AVIATION. Weak front across the central peninsula, south of KMCO, will continue to venture slowly southward through late day and into tonight. While lingering low clouds have finally burned off (most areas) there may still be tempo IFR/MVFR invof SCT-NMRS SHRA/TSRA this aftn/evening, generally south of a KMCO-KTIX line. Drier air from near KMCO northward so very little (ISOLD) rain chances here. With deep moisture southward and proximity to front wherever it takes up residency overnight, may have to monitor for some patchy fog/low stratus development (south).

MARINE.

Tonight . A weak cold front across central Florida will move slowly southward toward to just south of the Treasure Coast waters tonight. Small craft will need to exercise caution well offshore of Volusia and northern Brevard counties where a moderate northerly breeze, up to 15 knots, north of the front may still build seas to 6 feet into this evening. Otherwise, northerly winds will weaken overnight to 5-10 knots with seas 3-5 feet. Scattered showers and storms will continue to be possible over the coastal waters overnight, mainly offshore and south the Cape.

Friday-Monday . (Modified Previous Discussion) Weak cold front is expected to remain stalled near the Lake Okeechobee region Friday and Saturday, with scattered to numerous afternoon showers and lightning storms expected along to south of the front. Dry conditions will be present north of the frontal boundary. North to northeast winds around 10-15 knots through Saturday night, before diminishing to near 10 knots Sunday. A reinforcing front will cross the local area on Sunday afternoon, ushering in mostly dry conditions through the start of next week.

On Friday seas will be 3-4 feet nearshore and up to 5 feet offshore north of Sebastian Inlet. For this weekend into early next week, seas will be around 3-4 feet.

HYDROLOGY. The St. Johns River at Astor/ASTF1 is forecast to remain within Minor Flood Stage, at around 2.3 to 2.4ft through the weekend as a period of north winds should keep the water level higher there. At Geneva above Lake Harney/GENF1, the river will remain within Action Stage as it crests at 6.5ft this weekend.
